摘要： A developing unit, which is attachable to and detachable from a photosensitive member unit, includes: a developing roller; a housing in which a holding space that holds toner is formed; and a pressing receiving portion that receives pressing force from a pressing member. The housing includes a first bottom portion that projects toward an outer side of the holding space, and a second bottom portion that projects toward the outer side of the holding space, in a state in use. When viewed in a direction of a rotation axis of the developing roller, at least part of the pressing receiving portion is located in a space surrounded by the first bottom portion, the second bottom portion, and a tangent line tangent to both an outer wall of the first bottom portion and an outer wall of the second bottom portion.

摘要： A manufacturing method of a cartridge, the cartridge being attachable to an apparatus main body of an image forming apparatus, the cartridge including a first member and a second member, the first member including a receiving surface and a retaining portion, and the second member including a contact surface in contact with the receiving surface. In the manufacturing method, the first member and the second member are held so that the contact surface covers the retaining portion and so that the contact surface and the receiving surface are in contact with each other and joined by ultrasonic spot welding so that a recess recessed towards the retaining portion is formed in the second member and so that at least part of a fused portion of the first member and the second member enters the retaining portion.

摘要： A feeding device includes a first feeding member for feeding the developer in a feeding direction along a first rotational axis direction, the first feeding member being provided in a first feeding path and including a driving shaft and a drive transmitting portion, and a second feeding member for feeding the developer along a second rotational axis direction crossing the first rotational axis direction, and second feeding member being provided in a second feeding path and including a driven shaft and a drive receiving portion. The drive transmitting portion and the drive receiving portion engage with each other to deliver the developer from the first feeding member to the second feeding member. A bearing portion for rotatably supporting the second feeding member is provided in an upstream side with respect to the feeding direction.

摘要： An image forming apparatus includes an apparatus main-body to and from which a process cartridge can be attached and detached. The process cartridge includes an image carrying member to carry an image, a charging member to charge the image carrying member, a cleaning member to clean the charging member by contacting it, and a force receiving unit to receive a force for moving the cleaning member in a longitudinal direction of the image carrying member. The apparatus main-body includes a slope portion which slopes in a direction in which the process cartridge is attached and contacts the force receiving unit to apply the force in a process where the process cartridge is attached to the apparatus main-body, and the slope portion applies the force to the force receiving unit to move the cleaning member from an inside to an outside of a region where an image can be formed.
